Unboxing and First Impressions
Right out of the box, the Monster MQT39 comes with the basics — the earbuds themselves, a charging case, a USB cable, and a user manual.
Unfortunately, there are no extra ear tips included in the package, which is a disappointment since most earbuds with silicone tips usually provide at least two or three extra pairs. That’s definitely a negative point for those who want the best fit.
Design and Build
The charging case design is surprisingly nice — sleek, compact, and feels solid in hand. The earbuds themselves are lightweight and small, making them easy to carry around. Overall, the first impression is decent, especially for a budget product.
I found them quite comfortable for short listening sessions. They sit well in the ears and don’t feel heavy or intrusive.
However, it’s worth mentioning that these earbuds do not feature active noise cancellation (ANC). So, while they are comfortable, they won’t block out surrounding noise much.
Still, for casual use like commuting, watching videos, or light workouts, they feel perfectly fine.
Connectivity
The MQT39 comes with Bluetooth 6.0, which ensures fast and stable pairing. I connected them easily to my smartphone — the earbuds were recognized immediately and paired without any issues.
Sadly, there’s no companion app for sound customization or firmware updates. That’s a bit of a letdown, especially when even budget earbuds now often include basic app support.
Touch Controls
These earbuds rely on touch controls, and the response is surprisingly accurate.
Here’s a quick rundown of the main functions:
- Double-tap to play/pause music
- Triple-tap (right) to skip forward
- Triple-tap (left) to go back
- Tap and hold (right) to toggle Game Mode
- Tap and hold (left) to activate Voice Assistant
- Right earbud tap increases volume, left earbud tap decreases it
- During calls: Double-tap to answer or hang up, Hold to reject a call
The controls are simple and intuitive once you get used to them.
Microphone Test
The built-in microphone performs fairly well for the price range. Voices sound clear enough for calls or short recordings, though it does pick up some background noise in louder environments.
I tested it during a video call, and while it’s not studio quality, it’s more than good enough for casual use.
Sound Quality
Now, the part everyone cares about — how do they sound?
Honestly, I was pleasantly surprised. The MQT39 delivers clear and powerful sound with good bass performance. Even at higher volumes, the sound quality doesn’t distort much, which is impressive for such an affordable model.
The bass response feels punchy and deep enough for pop, hip-hop, and EDM tracks, while vocals and highs remain reasonably clean. It’s not “audiophile-level” quality, but for what you pay, it’s very good.
Battery Life
The Monster MQT39 offers around 24 hours of total playback when combined with the charging case. On a single charge, you can expect several hours of continuous use before needing to recharge.
While it’s not the longest battery life I’ve tested, it’s acceptable for its price bracket. The case charges via a standard USB cable — nothing fancy, but it gets the job done.
My Honest Verdict
If you’re looking for an affordable pair of earbuds that deliver solid sound and comfort, the Monster MQT39 might be worth considering.
Sure, it lacks premium features like ANC or app controls, but for casual listeners who just want something that works — it does the job well.
Would I recommend it?
✅ Yes, if you want good sound on a budget.
❌ No, if you need advanced features or high-end performance.
